To say the least, this release is highly backwards incompatible with sequins 0.4.x. Moreover, input data that was organized for 0.4.x needs to be organized slightly different in S3 or HDFS. You can read more about the new source root layout here.

Additionally, since v1.0.0rc1, a few issues have been fixed:

#60: A rare deadlock in the zookeeper code was fixed, and automatic GCing of old zookeeper nodes was added

#59: A bug was fixed where sequins would cancel in-flight proxied requests

#58: Sequins can now start up with no data, to make the quickstart guide simpler

This point release contains one minor change: instead of downloading data directly into the destination local dir, sequins will first download to a temporary dir and then rename the directory into place.

This is a hotfix release for a regression introduced in 0.4.1. In that version, the sync marker in sequencefiles could sometimes be read incorrectly, causing sequins to think that the file was corrupted.
